add wind PN

[lambaaryan011]

Pull Request

Description

This pull request adds functionality to fetch Physical Notification (PN) data for wind farms using the Elexon API. The script dynamically queries BM Unit data from the API and filters for wind farms based on the bm_unit column. It also retrieves PN data for the selected wind farm over a specified time range.

Changes:
⇾ Added a script (examples/wind_farm_pn.py) to fetch PN data for wind farms.

⇾ Integrated Elexon API (balancing_physical_all_get and balancing_physical_get methods).

⇾ Implemented filtering logic to identify wind farms dynamically from the API response.

Fixes #60

How Has This Been Tested?

The script has been tested locally by:

⇾ Fetching BM Unit data from the Elexon API.

⇾ Filtering BM Units dynamically for wind farms.

⇾ Retrieving PN data for a selected wind farm over a 24-hour period.
